Need some help with Trimming

I need a solution for the following problem: If I have a line, and a few rectangles crossing it, is there a command which can remove the line portions, which are contained in the reactangulars. Here's a snapshot of the things I'm trying to explain:

Just to add - I need to do multiple trimming with one command. Clicking inside every single rectangle is not a solution

EDIT: I corrected your link as it was broken

Type tr then hit enter 2 times, then select the trim lines.

Yes it works fine, but I need to trim out the line inside all the rectangles with less clicks, because on my project i have a line which is crossing... hmm about 200 rectangles and need to trim it. I know it can be done with array but I was wondering if there's a command similar to trim that can do the job.

My bad, not reading the question correct, I understand now you do not want to click every line one at a time, I think you need lisp to carry this one out.

if the rectangles are plines, you could use extrim (bonus tool, i mean express). just pick the pline, then pick inside the rec. and on to the next.

i'll look at extrim tomorrow and see if i can modify it to allow you to select multiples and just set to trim inside of closed objects, if time permits.

I tried the extrim command before but it nothing happens when I select the rectangle and click inside of it, althought it's a pline

Sounds like your lines and your rectangles are not in the same plane. Flatten your drawing and then try again.

I dont know of anyway of doing what your asking quickly with out writing a lisp routine... You could always just do a quick fix and use a wipeout on all the rectangles....the complete line will still be there but wont show through the rectangles..

Thats just a quick fix in case you neet to print it asap or something..

Here's a lisp called "CHOP", which trims everything in a window:

Chop.lsp

Thread moved to here, try out the lisp above and see how you get on.

it works pretty fine! Thank you very much : )

This post is an oldie but goodie!!

Could you modify your Chop routine to allow me to single select a rectangle?

I hope so....lol

Thanks,

It should be possible, if you search online there are LISPs out there that ill get you the corners of a rectangle, get them and replace P1 and P3 in the relevant part of the code and that should work.. Look for the part ";-CHOP WITH WINDOW" for P1 and P3,  then after the ((= P1 "W") line put in the select rectangle and get points P1 and P3 code from the internet and it should work.

however it is Sunday here, and CAD is off, so I can give you tips but not try anything for you

Using the EXTRIM (Express Tool) command you could select a rectangle and pick inside to trim inside.
